I have not been able to get a clean libstdc++ build on ppc64 for more than a month (since 2007-08-23). The failure is always the same. While building libstdc++/system-error.cc, I get:
/home/dnovillo/perf/sbox/gcc/local.ppc64/src/libstdc++-v3/src/system_error.cc:67: error: std::system_category causes a section type conflict Ben, that change seems to be yours. Any idea on how can I fix it? Or at least a workaround? Thanks.
